<DIV>For the last couple seasons, I've been using the Thunder Power 1010C/ 210V
Charger/Balancer system. I mostly use them </DIV>
<DIV>for charging 10 cell flight packs, but it will charge pretty much any
battery out there. It'll charge 10 cells at 5 amps. Or,</DIV>
<DIV>5 cells at 10 amps... 10 amps being the max output. As far as
input, the charger requires 11-15 volts... at a minimum of</DIV>
<DIV>15 amps, or 25 amps (at maximum charge output).. I use a 45 amp/ 12V
power supply that I either plug into availble 110V or</DIV>
<DIV>my Honda generator. With this setup, I can run two charger/balancer
sets at the same time, and pretty much continually fly</DIV>
<DIV>with short breaks of 10-15 minutes in between having packs ready to
go.</DIV>
<DIV> </DIV>
<DIV>These chargers are programmed with firmware and all updates are available
at the Thunder Power website. You simply connect</DIV>
<DIV>your charger to your computer, using the "available" connection cable and
download the new program into your charger.</DIV>
<DIV>There isn't a safer system out there as the balancer and charger are
connected together during the charge, and all individual</DIV>
<DIV>cell information is available for your viewing on charger screen.
</DIV>
<DIV> </DIV>
<DIV>It's a good idea to have a charger/balancer combo that allows the balancer
to "talk" to the charger during charging... If the </DIV>
<DIV>balancer detects a problem, it will notify the charger, the charge will be
stopped, and the charger will provide a trouble code</DIV>
<DIV>for your viewing... A typical situation will be that one or
more cells will be over volting, the balancer cannot bleed the voltage</DIV>
<DIV>fast enough and will tell the charger to shut down. Then, most of the
time, you can simply lower the charge amperage for a short</DIV>
<DIV>time, till the cells balance, then resume the normal charge. Most
every time I've had a shut down, it has been exactly that... a </DIV>
<DIV>cell imbalance where one cell reading is too high during the charge and the
charger shuts off. It's better to have to deal with that</DIV>
<DIV>for 20 minutes than to overcook a $500 battery! Or, overcook
the nearby area for that matter!</DIV>
<DIV> </DIV>
<DIV>In my oppinion, charging without a balancer can only lead to
problems. Everything works fine until there's a problem with one </DIV>
<DIV>of the cells.... That's when it gets hot. You won't ever know
there's a problem till it happens. If you use a system with</DIV>
<DIV>this protection, you may see the problem before it ever becomes a "REAL
PROBLEM"...</DIV>

charger needed</DIV>

<DIV>Does not having the balancers create any problems? What is the work
around for their absence?</DIV>
<DIV> </DIV>
<DIV>By the way, thanks for all of the great info, I am looking into the
features of all the chargers being discussed. I have always been careful while
charging but feel the need to be extra careful due to the potential volatility
of the Lipos.</DIV>
<DIV> </DIV>
<DIV>Thanks again</DIV>
